REGISTER.

.fication.

My invention relates to improvements in registers; and the object is toprovide means for preventing dust, which accumulates upon the doors,leaves, or valves, from being projeeted into the apartment by theinflowing current of air when the register is opened.

To thisend the invention consists in providing dust-troughs within theregister-casing and so related to the leaves that the dust accumulatedupon said leaves will be deposited into the troughs when the register isopened.

The invention consists, further, in certain peculiarities ofconstruction and arrangement, all of which will be hereinafter morefully described, illustrated in the accompany ing drawings, and definedin the appended claims.

In said drawings, Figure 1 is a perspective View of a floor-registerwith a portion of its cover-plate broken away to disclose the interiorparts. Fig. 2 is a transverse sectional view through the subject-matterof Fig. l, and Fig. 3 is a bottom plan view thereof.

Referring to numerals of reference employed to designate correspondingparts in the several views, 1 indicates a register-casing of rectangularor other form, preferably constructed of cast metal and having itsopposite side edges disposed inwardly to form dust-troughs 2, extendingfrom end to end of the casing, which latter is provided in one end wallat the ends of the troughs with openings 3, through which the dust maybe deposited by the tilting of the register when it is removed from timeto time for the purpose of cleaning. Immediately above the upturnedinner edges 4 of the trough 2 are disposed a pair of rock-shafts 5 and6, journaled in the end walls 7 and 8 of the casing 1 and supporting theouter edges of the movable leaves or valves 9 and 10, the free edges ofwhich overlap, when the leaves are closed, for the purpose of closingthe register to the passage of hot or cold air currents intended SerialNo. 19,768. (No model.)

for heating or ventilating purposes, as the case may be. The outer orhinged edges of these leaves are bent around the rock-shafts 5 and 6 ashort distance and are secured by rivets or pins 11, which insure theelevation or depression of the leaves to a vertical position, as shownin dotted lines in Fig. 2, or to the horizontal position, as shown infull lines in said figure. The leaves are retained in the closedposition bystops 12, projectingfrom the end walls of the casing andclosing the spaces between the leaves and the end walls, and said leavesare actuated by a valve-lever l3, pivotally mounted on the wall 8 of thecasing, as indicated at 14, and operatively connected with the leaves bymeans of links 15 and 16, pivoted to the lever 13, above and below thepivot of the latter,and con nected at their outer ends to short arms 17and 18, extending upwardly from the contiguous ends of the leaves 9 and10, adjacent to but not directly at their hinged edges. the lever 13,projecting above the cover-plate of the register, is moved to oneposition or the other the leaves or valves 9 and 10 are ele vated ordepressed to open or close the register, as the case may be, and byreason of the provision of the dust-troughs 2 any dust or other debriswhich may have accumulated upon the closed leaves will upon the openingof the register and the elevation of the leaves be deposited within thetroughs instead of being thrown back into the airfiues to be carriedinto the apartment with the current of hot or cold air passing throughthe register. This desirable characteristic of the device is broughtabout by two distinct variations from the usual construction of devicesof this character. The first and primary variation is'of course theprovision of the dusttroughs, and the other and almost equally importantvariation is the hinging of the leaves or valves at one edge instead ofat the center, this peculiarity permitting the troughs to be locatedpractically in the horizontal plane of the closed leaves and to receivethe accumulation from the entire area of said leaves as the latter arethrown into positions above the troughs by the opening of the register.

From the foregoing it will appear that I have produced a simple andingenious improvement in registers by means of which Thus when thehandle 18 of.

changes, modifications, and variations as may be comprehended within thescope of the protection prayed, as it is obvious that many ing providedwith dust-troughs, extending such variations may be effected withoutdeparting from the spirit of the inventione-as, for instance, theemployment of a greater number of leaves or valves and a correspondingincrease in the number of troughs. Ob-

.viously, also, the valves or leaves may be cast with trunnions insteadof being formed of sheet metal and riveted to the shafts, as shown.

What I claim is 1. In a register, the combination with a casing providedwith dust-troughs, of valves arranged to deposit dust accumulatedthereon into the troughs when moved to their open positions.

2-. In a register, the combination with a casing and a movable valve, ofa dustreceptacle located directly below the valve in one position onlyof the latter whereby dust accumulated upon the valve will be depositedin the receptacle when the valve is moved to a po- .sition thereabove.

' valve to receive the accumulated dust when the valve is opened.

ing and located adjacent to the hinged edge of the valve and in a lowerplane to receive the accumulation of dust from the valve upon movementof the latter.

5. In a register, the combination with a casing having the lower edge ofone of its walls inturned' to form a dust-trough, of a valve hinged atone edge immediately above the edgeof the trough to receive theaccumulation of dust from the valve upon its movement.

6. In a register, the combination with a casalong the lower edge ofcertain of its walls, Valves hinged 'at 'their edges immediately abovethe contiguous edges of the dusttroughs, and means for operating saidvalves to positions above the troughs to deposit accumulated debristherein.

7. A register-casing having the lower edges of its opposed side wallsinturned to form dust-troughs andprovided with openings in its wall tofacilitate the removal of accumulation from the troughs. V

8. In a register, the combination with a casing provided withdust-troughs, of hinged valves arranged to deposit dust accumulatedthereon into the troughs through the movement of the valves. i

9-. In a register, the combination with a casing provided withdust-troughs and having openings located at the ends of the troughs, ofhinged valves arranged to deposit dust accumulated thereon into thetroughs.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
